Overview
Anti-CACNA1B (CaV2.2) Antibody is an antibody targeting Voltage-dependent N-type calcium channel subunit α1B, Brain calcium channel III, BIII Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IHC, IP, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Voltage-dependent N-type calcium channel subunit α1B, Brain calcium channel III, BIII (also reported as Voltage-dependent N-type calcium channel subunit α1B, Brain calcium channel III, BIII).
- Immunogen/epitope region: Intracellular loop between domains II and III.
- Homology note: Mouse - 15/17 amino acid residues identical; human 11/17 amino acid residues identical; rabbit - 11/17 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- KO-validated: yes (validation context may be assay-dependent).
- Cited use: IP, IHC (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Voltage-dependent Ca2+ channels (CaV channels) are pivotal players in many physiological roles such as secretion, contraction, migration and excitation.1The voltage-dependent Ca2+ channels are composed of several subunits; α1, β, α2δ and γ. CaV channels were originally divided into six physiological types: L-, N-, P-, Q-, R-, and T-type.The CaV2.2 (formally named α1B) composes the α1 poreforming subunit for the N-type Ca2+ channel family. They are involved in neurotransmitter release from central neurons, including glutamate, γ-aminobutyric acid, acetylcholine, dopamine and noradrenaline.2The CaV2.2 is expressed preferentially in the central nervous system, where along with CaV2.1, it is responsible for pre-synaptic Ca2+ influx and neurotransmitter release.1,3The CaV2.2 channel is negatively regulated by many different GPCRs.
Research relevance and current trends
- Mapping receptor/channel localization across neuronal subtypes and subcellular compartments.
- Linking trafficking or surface expression changes to activity-dependent signaling and plasticity.
- Using KO/KD or blocking-peptide concepts to strengthen antibody-based target assignment.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Immunoprecipitation (IP): enrich the target for downstream detection or complex analysis (context-dependent).
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Conceptual control: KO/KD samples provide orthogonal support for target assignment when available.
- Provided control suggestions: Negative control: BLP-CC002.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
